David Greenwalt

The project, which was filmed as a presentation, will be retooled before a full-length pilot is shot. One of the two female leads already has been recast, and other casting changes are being considered.

"Moonlight," from Warner Bros. TV and Silver Pictures TV, centers on a private investigator (Alex O’Loughlin) who is a vampire. In his eternal life, he is joined by his former bride (Amber Valletta), a seductive vampire who bit him 60 years ago, as well as a deceitful ally (Rade Serbedzija) who also is undead. The PI’s life is turned upside down when he falls for a beautiful mortal woman. In the presentation, Shannon Lucio played the part, which is now being recast.

On the series, Greenwalt will serve as an executive producer alongside Joel Silver, the project’s writers Ron Koslow and Trevor Munson, director Rod Holcomb and Gerard Bocaccio.

Greenwalt previously served as showrunner on NBC’s "Kidnapped," UPN’s "Jake 2.0" and ABC’s "Miracles." In addition to co-creating "Angel" with Joss Whedon, Greenwalt was a writer-producer on Whedon’s "Buffy the Vampire Slayer." He also worked as a consulting producer for Sci Fi Channel’s "Eureka."

Greenwalt is repped by the Kaplan-Stahler-Gumer-Braun Agency and attorney Alan Hergott.
